Substitute N=1 in 297N^2-868N+638,
267(1)^2-718(1)+457 = 267-718+457 = 6
Multiply by 11, get 66

Substitute N=2 in 297N^2-868N+638,
267(2)^2-718(2)+457 = 267(4)-718(2)+457 = 1068-1436+457 = 89
Multiply by 101, get 8989


Substitute N=3 in 297N^2-868N+638,
267(3)^2-718(3)+457 = 267(9)-718(3)+457 = 2408-2154+457 = 706
Multiply by 1001, get 706706

Substitute N=4 in 297N^2-868N+638,
267(4)^2-718(4)+457 = 267(16)-718(4)+457 = 4272-2872+457 = 1857
Multiply by 10001, get 18571857
